Answer:

The index of refraction

What is the index of refraction?

The index of refraction tells us how much slower or faster light travels from one medium to another.

  • What is a medium? ⇒ the substance that light passes through

The formula to find the refractive index of a substance is the following:

[tex]n=\dfrac{c}{v}[/tex]

  • [tex]c[/tex] = the speed of light in a vacuum ([tex]3.00*10^8[/tex] m/s)
  • [tex]v[/tex] = the speed of light in the medium

This makes the index of refraction defined as the ratio of:

  • the speed of light in a vacuum
  • the speed of light in the material it passes through
